Embodiment 1

[0036] Embodiment 1: the preparation method of Baiji polysaccharide

[0037] Crush 100kg of dry white powder, directly add 200L of petroleum ether and stir for 20min, then let it stand for 1.5 hours to separate and remove the upper layer solution containing petroleum ether to obtain Precipitation I; add 250L of 85% ethanol aqueous solution to Precipitation I, stir and extract for 50min , let stand for 90min, remove the upper layer solution containing ethanol by layering, and obtain Precipitation Ⅱ. Add a certain amount of 300L water to the precipitate II, stir and heat to 85°C, keep warm for 35min, centrifuge at 5000rpm for 20min, obtain the supernatant, and remove the precipitate. Concentrate the supernatant under reduced pressure at 50-65°C to 1 / 20 of its original volume, then add 95% ethanol to a final concentration of over 75%, ethanol precipitation for 10-20 hours, and filter once with a 0.22 μm ceramic membrane to obtain a filter residue That is white and polysaccharide...

Embodiment 2

[0038] Embodiment 2: Preparation of cosmetic and whitening products

[0039] Take 15 grams of acrylic acid, add 100 grams of water, after the acrylic acid is completely dissolved, add 10 grams of white polysaccharide to dissolve, and get about 100 mL of the mixture; then add 25 μL of 10% ammonium persulfate and 20 μL of TEMED to the mixture, mix quickly and place it at room temperature After 2 hours, wash three times with 500mL of water to obtain jelly; then add 60 grams of white polysaccharide and 15 grams of dihydromyricetin to the jelly, stir and mix evenly, immediately treat with ultrasonic wave for 40 minutes, and vacuum dry to make it The water content is reduced to about 20%, and 120 grams of beauty and whitening products are obtained, which are stored in vacuum packaging for subsequent use.

Embodiment 3

[0040] Embodiment 3: Preparation of cosmetic and whitening products

[0041] Take 30 grams of acrylic acid, add 150 grams of water, after the acrylic acid is completely dissolved, add 15 grams of white polysaccharide to dissolve, and get about 150 mL of the mixture; then add 35 μL of 10% ammonium persulfate and 30 μL of TEMED to the mixture, mix quickly and place it at room temperature After 3 hours, rinse three times with 600mL of water to obtain jelly; then add 120 grams of white polysaccharide and 35 grams of dihydromyricetin to the jelly, stir and mix evenly, immediately treat with ultrasonic wave for 40 minutes, and vacuum dry to make it The water content is reduced to about 25%, and 260 grams of beauty and whitening products are obtained, which are stored in vacuum packaging for subsequent use.

Abstract

The invention relates to a composite formula obtained through compatibility of bletilla striata polysaccharide and dihydromyricetin for beautifying and whitening. Acrylic acid is prepared, water weighing 4-15 times of the weight of acrylic acid is added, bletilla striata polysaccharide is added to be dissolved after complete dissolution of acrylic acid, then 10% ammonium persulfate and TEMED are added to the mixture, quick mixing is conducted, them the product is placed at room temperature for 1-3 h, flushing is conducted three times with three to five times volume of water, bletilla striata polysaccharide and dihydromyricetin are added to be evenly stirred and mixed, then ultrasonic treatment is conducted instantly for 20-50 min, and water content is reduced to a level below 20-30% through vacuum drying. The solubility of dihydromyricetin can be remarkably promoted by bletilla striata polysaccharide, the acidness of the solution is guaranteed, and the stability of dihydromyricetin is facilitated.

Description

Technical field: [0001] The invention relates to the application of a whitening polysaccharide and dihydromyricetin composition in cosmetic and whitening, and belongs to the technical field of natural medicine application. Background technique [0002] Dihydromyricetin is one of the main active ingredients of the snake grape, also known as vine tea. It is a traditional folk medicine and has been widely used in the treatment of skin diseases, boils, osteomyelitis, acute lymphitis and other infectious diseases. Inhibit a variety of harmful bacteria. The solubility in water at 25°C is 4%, and the solubility in hot water is even greater; easily soluble in methanol, ethanol and acetone, very slightly soluble in ethyl acetate; hardly soluble in chloroform and petroleum ether. Lin Shuying and others investigated the stability and influencing factors of DMY, and confirmed that the dihydromyricetin solution is prone to oxidation and has poor stability. It can maintain its chemical s...
